JAMES SELEY, or PEOEIA, ILLINOIS.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 274,981, dated April 3,1883. Application filed November 3, 1882.` (Model.)

To alt whom it may concern:

Be it known that I, JAMES SELBY, of Peoria, in the county of Peoria, inthe State of Illinois, have invented an Improvement in Corn-Planters;and I do hereby declare that the following is a full, clear, and exactdescrip tion thereof, reference being had to the annexed drawings,making a part of this specication, in which like letters of referencerefer to like parts, and in which- Figure 1 represen ts a verticalsection through `it w,- Fig. 2, a sectional plan through y y.

My invention is in that class of corn-planters in which a horizontaldisk containing openings therethrough is secured in the bottom of theseed-box, and, being intermittently rotated by means of gravity-pawlsengaging with lugs at the circumference of said disk and pivoted to ahorizontally-reciprocating bar, controls the dropping of the corn fromsaid seed-box.

My improvement relates to the `means of intermittently rotating theperforated disk, to the stoppin g of said disk after each movement, andto the shut-oft'l'ieneath which is the Seedopening through the bottom ofthe seed-box, whereby no more corn is allowed to pass downward than isin any one of the disk-perforations. In the drawings, G is the seed-box;A B, the disk, having openings A' B; P P', the gravitypawls, pivoted atPzand P3 to arms extending laterally from the slide-bar E. H L is thebottom ot' the seed-box, and has through it a threefourths annularopening, beneath which come the perforations of the disk A B. Thisbottom H L is not shown in plan in the drawings, but only in verticalsection in Fig. 1.

'My disk A B, I make in two parts, A and B, each ot' which has the samenumber-usually ten-of trauSradially-elongated openings A' and B'. Theupper thin disk, A, is rotative about a central projecting boss, B2, oftheV disk B, and is bound to` said d-isk B by the This is for thepurpose of allowing the size of the openings A' B' to be changed to snitdifferent kinds of corn by turning slightly the one upon the other tobring the opposite sides of any two of said openings toward or from eachother. The boltholes in one of the thin disks, being elongated, permitthis adjustability. This disk A B rests upon the transverse plate D, andis held in place thereon by the pin I, projecting through the center ot'the said disk A B. Said plate D is `entirely plane on its uppersurface,buthas one opening, D2, through which the corn held in anydisk-opening A B' above it can descend to the heel of the planter-shoe.`From the under disk, B, project radially ve lugs, the upper faces ot'which all slope in the same direction to permit the pawls P P' to slideup over .them the more readily. Although the pawls are pivoted at P2 andP3 toward the same end of the slide-bar E, they are enabled to rotatethe disk A B in the Same direction by making one of them a push-pawl, P,and the other a pull-pawl, P', being hook-shaped.

To prevent the disk A B from being turned too far, a stop-lug, F, isfastened to the slidebar E at each side of the diskA B, at such a pointthat each slide of the bar E brings one of Said stops F immediately infront ot' one ofthe lugs C, as soon as the disk A B has been moved byone of the pawls P. If', however, through any cause, the slide-bar Eisnot moved far enough, the disk A B Will be so left that one of the lugsG lies directly in the path ot' one of the Stops F at the next movementot' the bar E, and Something would have to break. To remedythis I havethe said stops F vertically movable in slots cut through the bar E andpressed up in position by springs S. Now, it'the said lugs C are in theway ot' one of' the stops F the latter is simply pushed downward, or, ifthe other construction be used, backward, and no injury is done. Theslide-bar E rests upon rollers N N, supported by the tracks M' M',depending from the skeleton frame M.

The bottom H L. below which is the disk A B and other mechanism justdescribed, has through it, as previously mentioned, an annular openingconcentric with the disk A B. Said opening does not make an entirecircle, but only about three-fourths of one, and is at the same distancefrom the center of the disk A B as are the openings A' B', so that allof said openings A' B' are uncovered to the corn inthe seed-box, exceptthe one or two beneath the solid one-fourth part that makes up theremainder of the three-fourths annular opening aforesaid. This saidone-fourth part is directly IOC over the opening D2 through the plate D,and operates, ofcourse, to prevent more corn dropping through an openingA' B', which comes thereunder, t-han is contained in said A B'..

To prevent any grains of corn which may project partially upward fromthe others contained in A' B', from being cut in two as the revolutionof thedisk A B carries them under the edge of the said solid one-fourthpart, I have constructed ahammer-shaped cut-off, J, held down ,almostagainst the disk A B by a spring, K, and kept from touching said disk bythe stop L'. The said solid one-fourth part or bridge L, beneath whichis placed said cutolic J, is elevated sufficiently to allow therequisite vertical play of said cut-oli" J. The object of the arm J' oi'the cut-oii'J is to prevent the admission of grain into the spacebetween the said cut-off J and the bridge L. It will be observed thatthis construction ofthe cutoi J is free from the. serious defect ofbecoming clogged by any grain of corn getting crowded between it and anypart of the bridge L. Were the bridge L in the form of an inverted cupup into which a flat mit-off could 4 be pressed a grain of corn couldeasily get 2. In a seed-dropping mechanism for cornplanters, adisk-stop, F, secured to the slidebar E, and adapted to offer resistanceto transverse butnot to longitudinal pressure relative to saidslide-bar, for the purpose set forth.

3. The compound disk A B, having perforatons A' B', andradially-projecting lugs C, in combination with the gravity-pawls P P',pivoted to the slide-bar-E, substantially as and for the purposespecified.

4. The two disks A and B, having radiallyprojecting lugs C, andtransversely-elongated openings A' B', and bolts A2, in combination withthe supporting-plate D, the slide-bar E, having depressible stops F, andthe gravity push and pull pawls P P', substantially as and for thepurpose described.

5. In corn -planter seed -dropping mechanism, the bottom, H, havingpartial annular opening and elevated bridge L, and the harnmer-shapedspring-actuatedcut-off J, in combination with the perforated disk A B,having lugs C, the gravity push and pull pawls P P',

and the slide-bar E, having spring-stops F,

substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing invention I have hereunto set myhand this 21st day of October, 1882.
